I tried to hear my HDMI audio from my discrete card GTX 1050ti to my monitor LG ULTRA sharp 60Hz@4k, following this guide but it has not worked, someone could help me see what I do wrong, thank you. [my sound work great from mother board, with cloverHDMI, but my real problem is use the HDMI to the LG monitor speaker.]

@b31k,

After upgrading to MacOS 10.13.6 on my desktop video editing system I had similar issues trying to get HDMI audio working on my Nvidia 980 Ti which is connected to a LG 34" 21:9 Monitor, the only solution that worked for me was to use AppleALC which supports almost all Nvidia HDMI audio. I would also recommend installing WhatEverGreen.

Both are covered in this guide :-

https://www.tonymacx86.com/threads/an-idiots-guide-to-lilu-and-its-plug-ins.260063/

As detailed in the guide you will need to remove any existing clover patches, enabler kext's .. etc, if you follow the guide carefully it should work for your configuration, you can also use AppleALC for your audio codec this reducing the number of 3rd party kexts and clover patches.

Cheers
Jay

@jaymonkey,

Thank you very much for answering.
I tried but AppleALC no work HDEF in Ioreg show 0x8086A170 (INTEL) instead Nvidia HDMI

Something is wrong, if a substitute IntelGraphicsFixup.kext, NvidiaGraphicsFixup.kext, Shiki.kext by WhateverGreen.kext (last version) + AppleALC.kext

All look run fine but when , search for "hdau" in ioreg not show, think codec not recognised.

Post #1 IOReg shows macOS/Nvidia HDMI audio working. Nvidia web driver is not working, see AppleHDA HDMI Audio/Post #1/Notes/Nvidia.

Each method you tried works, however, an active DP2HDMI adapter (4K) is the only way to solve Nvidia's problem; no guarantee.

The method does not matter as no method solves the no HDMI audio on a Pascal HDMI connector.

I tried first DP(monitor) to DP(card),HDMI(monitor) to HDMI(card) and HDMI(monitor) to DP2HDMI adapter, this isn't active adapter and show in 1080p (Full HD) this is the problem?

No DP audio, replace graphic card, if possible
GTX 1050ti (EVGA 04G-P4-6253-KR) supports DP audio only
toleda,

Hello, sorry but I do not understand

My card is exactly GTX 1050ti (Palit Kalm NE5105T018G1H) have 3 ports include DP port, if this support audio.
This port should work direct connection to DP (tv) or by DP2HDMI to DP(tv)
I am wrong?

On the other hand I have seen that, when I start with the dp cable it does not recognize nothing, but if I change to hdmi recognizes it but it does not sound anything.

Windows, no; macOS, yes

You have validated Nvidia's macOS/Pascal driver problem, no HDMI audio on boot. HDMI audio on HDMI connector hot plug.
No sound, verify volume control on the monitor.
